title: Short-term and mid-term results with the Sorin Freedom Solo aortic valve.
abstract: OBJECTIVE
  The study aim was to present the short- and mid-term results for patients who underwent aortic valve replacement (AVR) with the Sorin Freedom Solo third-generation stentless prosthetic valve.
  
  
  METHODS
  AVR with a Sorin Freedom Solo valve was performed in 14 patients between March 2006 and March 2011. Patients aged > or = 60 years (male:female ratio 6:8; mean age 73.28 +/- 5.42 years) who required AVR with the Sorin Freedom Solo valve according to the surgeon's choice were included in the study. The valvular prosthesis was implanted in the supra-annular position, using a single suture line.
  
  
  RESULTS
  Eight patients underwent an isolated AVR; combined interventions were carried out in the other patients due to concomitant cardiac disease. One patient died during the immediate perioperative period, and two more during the follow up, from non-cardiac causes. The mean maximum transvalvular gradient of patients with aortic stenosis was 88.1 +/- 20.2 mmHg, and this fell to 26.4 +/- 7.6 mmHg during the early postoperative period. The mean gradient at one year of follow up was further decreased to 19.4 +/- 5.3 mmHg. The left ventricular end-diastolic and end-systolic diameters were also significantly reduced, from 4.8 +/- 0.9 to 4.3 +/- 0.6 cm and from 3.2 +/- 0.6 to 2.8 +/- 5.3 cm, respectively. The average left ventricular ejection fraction was 60.2 +/- 4.9% preoperatively, and 63.2 +/- 2.1% at one year after surgery (p = NS). No paravalvular leakage, endocarditis, prosthesis failure or neurologic events were reported among patients.
  
  
  CONCLUSIONS
  The Sorin Freedom Solo stentless valve has provided good early and intermediate-term results. Implantation of the prosthesis is straightforward, with low rates of morbidity and mortality. However, these data require further support from larger patient series and long-term follow up.
